hlyihventiori relates to an inking devi 'ee for the types of type writing and similar mathe machine in sucha manner-that it projects onto the path of the typerod or type lever and is thrown by thejsaine against a pad impregnated with liquid ink from a reservoir. The ink roll takes the. required amount of ink and transmits the same to thenextfollowing depressed type when the roll is returning to its initial position; The ditliculty consists in maintaining a uniform impregnation of the ink pad in order that the ink roll is charged with always the same quantity of ink when striking against the pad so that only so much ink is-securely transmitted'onto the type as is necessary forthe production of a clear copy. :It is further important that the ink roll adjusts itself accurately to the centre of the type, and with this object in view the device is 'shiftable on its holder in horizontal direction. The ink reservoir must 7 alsobe adjustably mounted on a holder in order that it may be uniformly us'ed'on any typewriting machine.

- in essential. characteristic feature ofthe invention consists in that the ink is supplied to theink-pad in a quantity capable of being easily regulated. The regulation can go up to completelyshutting off the supply of the ink'to the pad, this taking place whenthe typewriting machine is not to be used. a p An 'embodimentof he invention isillustrated byway of example in the accompanyingdrawing in which .1

liquid absorbing material is jammed in an aperture of the Wall of reservoir w, said reservoir being preferably of oval shape. A

Wick 1 is located in a channel a of the Wall of the reservoir w leading to the ink pad .2,

The operation is as follows; The-depressed type guided on the guide plate a strikes against tlie ink roll a and' throws this-ink roll,

r in opposition to the action ofthe spiral spring 'znagainst the ink'pad a so that the ink roll -takes ink from thepad z to which theink is supplied froin'the reservoir' w by the Wick 1 i this ink being then transmitted'to the de-' atype.
